HOSPITAL BED Aug. 15, 1933.

2 Claims.

This invention pertains to hospital beds.

One of the objects of this invention is to provide apparatus in connection with hospital beds whereby a patient may be served with a pan in a convenient and expeditious manner.

Another object is to provide such apparatus which may be used with a minimum of discomfort to the patient.

Another object is to provide such apparatus which may be applied to the bed in such a way as to be out of the way when not in use.

Another object is to provide such apparatus which is attached to one side only of the bed so as to leave the other side free.

Further objects will appear from the following description taken in connection with the accompanying drawing in which:

Figure 1 is a side view of a hospital bed embodying this invention.

Figure 2 is a fragmentary sectional view taken on line 2-2 of Figure 1.

Figure 3 is a bottom plan view of the detachable seat.

Figure 4 is a front view of the adjustable table,

and

Figure 5 is a detail of the crank construction. Referring to the drawing, 1 designates the bed frame of a hospital bed of any suitable type. The bed is preferably provided with a movable head rest 2, pivoted at 3 on the bed frame and having elevating means such as a toggle 4 which may be operated through connections 5 of any suitable type by a crank 6.

Similarly, a movable foot rest 7 may be provided with elevating means 8 and operating connections 9 operated by a crank 10. The above devices may be of any well known type. In accordance with this invention there is mounted on one of the side members of the bed frame 1, a housing 11 adapted to contain and support elevating mechanism. This elevating mechanism comprises a pair of vertical guides 12 extending upwardly from the housing 11 and adapted to guide a pair of vertical sliding posts Serial No. 558,692

15. Any other suitable mounting course, be employed.

Mounted in the housing 11 is a pair of guide rods 16, upon which the yoke 14 is adapted to slide and which provide additional support and rigidity therefor. There is also mounted in the housing 11, a vertical elevating screw 17, hav ing a threaded connection with the yoke 14, or otherwise connected for elevating said yoke. The upper end of the screw 17 is provided with a beveled gear 18 engaging a similar beveled gear on a shaft 19, having a bearing in the outer wall of the casing and having mounted on its outer end, a crank 20. As shown in Figure 5, the shank of the crank 20 passes through the shaft 19 and is traversed by a locking pin 21. A spring 22, on said shank, maintains the pin 21 in one or the other of a pair of locking grooves or notches in the shaft 19 so that the crank may be turned to operative position as shown in Figure 2, or to in-operative position as indicated by dotted lines in Figure 5. By turning the crank 20, the beveled gears are operated to turn the screw 17, thereby raising or lowering the yoke 14 and therewith the posts 13.

A suitable seat 23 is provided on the bottom face thereof with a pair of rails 24, each equipped at one end with a socket 25 adapted to fit over the upper end of one of the posts 13. The rails 24 are each equipped at its other end with an inwardly extending supporting flange 26 and a stop flange 27. The sockets 25 are formed with ample strength and the rails 24 provide cantilever members by which the seat may be supported in horizontal position when the sockets are placed over the ends of the posts 13.

A pan 28 is provided having outturned marginal flanges 29 at its side and rear edges and a handle 30 at its rear end. The outturned flanges at the side are adapted to be inserted 5 upon and supported by the flanges 26 and the rear flange is adapted to take over a spring latch 31 on the rear edge of the seat 23.

In the use of this device, the patient is rolled to the right side of the bed as seen in Figure 2; With the posts 13 lowered to a suitable position, the seat 23 is then mounted thereon by placing the sockets 25 over the ends of the posts 13. The seat is then adjusted to lie flat upon and even sink into the mattress 32 and the patient 195 is rolled back to the left side of the bed so as to rest on the seat. The seat may now be elevated by operating the crank 20. During this operation the patient may assume a sitting posture, or may recline against the head rest 2.

may, of

When the seat has been elevated to the proper height, the pan is attached by inserting the flanges 29 over the flanges 26 and moving the pan forward against the stops 27. The rear flange is then engaged with the latch 31. The pan is disengaged by simply tripping the latch 31, which allows the pan to drop down upon the bed. It may then be removed endwise, after which the seat may again be lowered and the patient returned to the bed.

In accordance with this invention, the device may also be used to support a table for reading or eating. The table is illustrated in Figure '4, and comprises a top 33, mounted by an adjustable connection 34 upon a socket 35. This socket is arranged to fit overone of the posts 13. The upper end of the posts may be provided with a slot 36 adapted to receive a key pin 37 in the socket 35, so as to keep the table from pivoting on the post. The adjustable connection 34 is such as to permit the table to'be adjusted to any convenient inclination for reading or otherwise. At the same time the posts 13 may be raisedor lowered so as to adjust the height of the table.

It may be seen .that this I invention provides .a

simple and convenient mechanism for handling he may be permitted to lie on one side of the bed at ease While the device is being adjusted on the other side and then by a simple rolling movement can be transferred to the device.

The use of this device in combination with a bed having movable headand foot rests makes it possible to combine a considerable number of different operations by suitable manipulation of these different devices.

While this invention has been described as a unitary device, it will be understood, of course, that various individual features or sub-combinations thereof may be useful by themselves without reference to other features and accordingly the employment of such individual features and sub-combinations'is contemplated by this invention and within the scope of the appended claims.

It is further obvious that various changes may be made in the details of construction, within the scope of the appended claims without departing from the spirit of this invention;

it is understood, therefore, that this invention is not limited to the specific details shown and/or described.

Having thus described the invention, what is claimed is:

1. A hospital bed having a'bed'frame, ahousing rigidly supported on one side of said frame, elevating .mechanism in .said housing including a vertically slidable post, a cantilever detachably mountable on said post to overhang only that side of the bed on which it is mounted, a seat supported by said cantilever, and a pan removable to the under side of said seat.

7 2. A hospital bed having a bed frame, hoisting mechanism rigidly mounted on one side rail only of said frame including a vertically slidable post and means for elevating the same, and a seat supported on said post to partially overhang the bed on that side on which-said mechanism is mounted so as to leave the other side of the bed clear.
